[BUGFIX] TypoScript stripProfile not forwarded to ProcessedFile

The TypoScript stripProfile feature not forwarded to
ProcessedFile anymore. Example of the feature that has
been available in TYPO3 CMS 4.x:

10 = IMAGE
10.file = fileadmin/images/image1.jpg
10.file.stripProfile = 1

The protected method modifyImageMagickStripProfileParameters()
does not make any sense anymore since the actual ImageMagick
processing has been moved around in TYPO3 CMS 6.0.

Fixes: #47145
Releases: 6.0, 6.1
